   BioCE Consult - shared stylesheet for the DARK pages (landing + track)
   consult.bioce.cloud · PureYo dark design language

   DESIGN LOCKS (do not drift):
   - ACCENT LOCK: teal is the one accent everywhere. --teal for fills/borders/
     focus, --teal-l for text/links/eyebrows (brighter, keeps WCAG AA on navy).
   - RADIUS LOCK: 12px interactive controls (buttons, inputs, tiles, toggle);
     16px cards/panels/containers; 999px pill chips + badges (PureYo chip
     language). No other radii.
   - THEME LOCK: this file is deep-navy dark only. The legal pages
     (/privacy/, /terms/) ship their own self-contained light warm-paper theme
     and do NOT load this file.
   - MOTION: level 3 - CSS hover/active state feedback plus one gentle scroll
     load-in, all gated behind prefers-reduced-motion: no-preference.
   Fonts: Sora (display) + Inter (body) + Noto Sans Thai, loaded per page via a
   Google Fonts <link> (deliberate estate pattern). No external JS/CDN.
